Abstract

The present invention relates to a coil housing of a solenoid for an electromagnetic clutch of an automobile. According to the coil housing of the solenoid for the electromagnetic clutch of the automobile of the present invention, a piston and a coil assembly are charged inside a housing main body in which a bushing is coupled to an inner wall of a (┘└)-shaped lower housing. In addition, an upper part of the housing main body is sealed with a (┌ ┐)-shaped upper housing, and is fixed by mutual stacking. According to the present invention, since the coil housing is configured to be divided into the upper housing and the lower housing and assembled, it can be manufactured by drawing. Therefore, as a result of shortening a manufacturing process, a manufacturing cost of the coil housing may be reduced.
